I have a DP/MC blaster, and I take Suppressive fire, fully proc'd out with Apocalypse chance for -energy, GW chance for psi, Unbreakable chance for Smashing, Neuronic chance for psi, and Gladiator's Net chance for lethal, and Gladiator's Javelin chance for Toxic.
I really love suppressive fire with procs because it has like zero animation time, especially compared to the other ST attacks in the set. It's the quickest firing attack (though admittedly, I haven't tried Pistols). I love it as a proc bomb. It hits like an absolute truck for damage, especially related to it's animation time.
